Well, I am no expert but it looks decent to me. I have seen a couple of tests in magazines where that head and cam combo has made above 400 hp so the power rating is feasable. I dont know what kind of price would be fair on it. I dont know anything about the company but accoding to their description it sounds like they did a good job.

One thing though is if you do buy this and put your tpi on it I would change the cam. That cam is a real good cam, but not for tpi. It has a 110 lobe seperation. This will work(I have rode in a tpi car with this cam but the chip had some work done to it) but it will work a lot better with the computer if you get a lobe seperation of at least 112. Also, you wont make that much power through the tpi simply because the tpi doesnt flow at high rpms(4500 and up it really starts to hinder performance) and that cam is supposed to peak at I think 5800.

Thats about all I see. Well, it does appear that he does get a lot more good reviews on ebay than bad but he has had some bad so you may want to read those and see what others that have purchaced from him thought.

yea i was wondering about the cam setup there any specific suggestion you know of for the cam? there are so many i get easily confused but i hope this does woprk out because i would like this engine

 

Is this for the 91 with 5 speed you list in your sig? Do you know what rear gears it has? Also I just noticed that this is not a roller motor. That is not a problem, just something I thought I would point out. As far as the cam, I prefer comp cams. Both comp and crane cams have cams designed for computer controlled cars. If you go here: http://www.compcams.com/Products/54-89.pdf
go to page 34. There are the computer controlled cams. You would need flat tappet. I would go for the larger of them but thats also a choice you will need to make. Maybe someone else will have more information to offer. You could also get almost any cam specs you want custom ground with the larger lobe seperation if you dont find one you like.

yea this is for the 91 Z i dont know my gears exactly but this car will have a complete performance rebiuld. engine, t56 tranny, new clutch and flywheel driveshaft and i was thinking about putting 3.73 gears or maybe 3.42's in it i still need help on that aspect too. but ill have my suspension done and brakes before summer i think then i was gonna start on my engine but i saw this and i didnt want to pass it up so as far as the gears i could get whatever i needed to match the cam. right now this POS is only gettin 13 mpg's for some reason so mileage doesnt really matter to me that much, just speed!

 

I have heard alot of bad stuff about this guy in other forums check his feedback and be careful
